Abstract: 1406986 Motor torque control BURROUGHS CORP 25 Jan 1974 [30 March 1973] 03490/74 Headings H2J The torque produced by a servo-motor is kept constant despite speed changes, by the provision of a motor speed sensing means, a servo amplifier providing input voltage to the motor, and switching means responsive to the speed sensing means for switching the input of the amplifier from a voltage representing either a predetermined maximum motor voltage or a motor-speed sensitive voltage, to a voltage representing the motor armature current. In a first embodiment, the motor is started from rest by the application of a constant, maximum voltage to the amplifier. The motor accelerates without constant torque until a first speed S 1  is reached whereat a latching circuit responsive to the speed sensing means, e.g. a tachogenerator, causes a transistor switching circuit to apply a voltage derived from the armature current to the amplifier input whereby the speed of the motor may vary at constant torque. If a lower speed S 2  is attached, the latch reverts to its former state and the motor is accelerated back to S 1  by means of the constant voltage. In a second embodiment, a second amplifier having a gap equal to the damping constant of the motor is provided between the first amplifier and the starting voltage input to which input is also added the tachogenerator output.
